1997 Chevy Tahoe with 5.7l
What I have done...
3 years ago I replaced spider injectors. Have had no problems since until six months ago I started feeling the truck sputter. I replaced the fuel pump and that worked for a bit. Sputter started again felt different this time.
So I
Checked fuel pump again.
Check fuel pressure.
Changed map sensor.
Changed fuel pressure sensor.
Changed cap and rotor. That worked for like a week.
Changed the whole distributor.
Checked ground everywhere.
Changed plugs and wires.
Adjusted timing.
Changed throttle position sensor today ... right after that it shifted really hard and it still sputters under load but not in park. Any suggestions?
